While the choice ultimately depends on the couple's specific needs and circumstances, oral contraceptive pills (OCPs) are often a suitable option for many couples.</li><li>↳ OCPs (Oral Contraceptive Pills): OCPs are a highly effective form of contraception when used correctly. They provide reliable pregnancy prevention, are convenient to use, and have additional benefits such as regulating menstrual cycles, reducing menstrual pain, and improving acne. OCPs can be started immediately and discontinued when the couple decides to conceive.</li><li>↳ OCPs (Oral Contraceptive Pills):</li><li>↳ Incorrect Options:</li><li>↳ Incorrect Options:</li><li>↳ Option B: Condoms: Condoms are a barrier method of contraception that provide protection against both unintended pregnancies and sexually transmitted infections (STIs). They are easily accessible, affordable, and do not require a prescription. Condoms can be a good option for couples who prefer non-hormonal methods or need STI protection in addition to contraception. However, they may have a higher failure rate compared to hormonal methods like OCPs.</li><li>↳ Option B: Condoms:</li><li>↳ Option C: Sterilization: Sterilization, such as tubal ligation for women or vasectomy for men, is a permanent method of contraception. It is considered a long-term and highly effective option for couples who have completed their desired family size or do not wish to have biological children. Sterilization should be approached as a permanent decision, as reversal procedures are costly and not always successful.</li><li>↳ Option C: Sterilization:</li><li>↳ Option D: IUD (Intrauterine Device): IUDs are long-acting reversible contraceptives that offer highly effective contraception for an extended period. They can be a suitable choice for couples who desire long-term contraception without the need for daily or frequent user involvement. However, IUDs require a healthcare provider's insertion, which may not be immediately accessible for a newly married couple.</li><li>↳ Option D: IUD (Intrauterine Device):</li></u\n<p><strong>References:</strong></p>\n<ul><li>↳ Importance of Family Planning: Newly married couples may have different aspirations and plans for their future. Family planning through contraception enables them to establish a strong foundation in their marriage, pursue education or career goals, and ensure emotional and financial stability before starting a family.</li><li>↳ Choice of Contraceptive Methods: There are various contraceptive methods available for newly wedded couples. The choice of method depends on factors such as effectiveness, convenience, personal preferences, health conditions, and future pregnancy plans. Some commonly used methods include: a. Barrier Methods: These include male and female condoms, diaphragms, and cervical caps. They provide a physical barrier to prevent sperm from reaching the egg. b. Hormonal Methods: These include combined oral contraceptives (COCs), progestin-only pills (POPs), contraceptive patches, injections, implants, and hormonal intrauterine devices (IUDs). They work by altering hormone levels to inhibit ovulation, thinning the uterine lining, and thickening cervical mucus. c. Intrauterine Devices (IUDs): These small, T-shaped devices are inserted into the uterus to prevent pregnancy. They can be hormonal (releasing progestin) or non-hormonal (copper-based) and provide long-term contraception. d. Sterilization: Permanent methods like tubal ligation (for women) or vasectomy (for men) can be considered if the couple has completed their desired family size.</li><li>↳ Counseling and Education: Newly wedded couples should receive comprehensive counseling on different contraceptive methods. They should understand the benefits, effectiveness, possible side effects, and proper usage of each method. Couples should also be aware of emergency contraception options in case of contraceptive failure or unprotected intercourse.</li><li>↳ Dual Protection: Newly wedded couples may also consider using dual protection by combining two methods, such as using condoms along with hormonal contraceptives. This provides added protection against unintended pregnancies and reduces the risk of sexually transmitted infections (STIs).</li><li>↳ Regular Follow-up and Reassessment: Couples should have regular follow-up visits with a healthcare provider to assess the effectiveness of the chosen contraceptive method and address any concerns or side effects. As their needs may change over time, periodic reassessment of the contraceptive method may be necessary.</li><li>↳ Communication and Shared Decision-Making: It is important for newly wedded couples to openly communicate about their contraception preferences, concerns, and future plans. Shared decision-making ensures that both partners are actively involved in choosing the most suitable contraceptive method for their unique circumstances.</li></u\n\n<p style='font-size: 10px; color: #808080; font-style: italic;'>@dams_new_robot</p>", "bot": "@dams_new_robot", "audio": "", "video": ""}, {"text": "What should be the minimum rate of couple protection in order to achieve the demographic target of NRR = 1?

It quantifies the test's ability to correctly detect individuals who have the condition or disease being screened for.</li><li>↳ The sensitivity is calculated using the following formula:</li><li>↳ Sensitivity = True Positives / (True Positives + False Negatives)</li><li>↳ True positives refer to the number of individuals who have the condition or disease and are correctly identified as positive by the screening test. False negatives refer to the number of individuals who have the condition or disease but are incorrectly identified as negative by the screening test.</li><li>↳ To calculate the sensitivity, you need the values of true positives and false negatives. These values can be obtained by comparing the results of the screening test to a reference standard or gold standard test.</li><li>↳ For example, if out of 100 individuals who truly have the disease, the screening test correctly identifies 80 as positive (true positives) and misses 20 (false negatives), the sensitivity would be:</li><li>↳ Sensitivity = 80 / (80 + 20) = 80 / 100 = 0.8 or 80%</li><li>↳ So, in this case, the sensitivity of the screening test would be 80%.</li></u\n\n<p style='font-size: 10px; color: #808080; font-style: italic;'>@dams_new_robot</p>", "bot": "@dams_new_robot", "audio": "", "video": ""}, {"text": "A large number of tests were done in series.
